NASA and Boeing engineers are evaluating results from last week’s engine tests at NASA’s White Sands Test Facility in New Mexico as the team works through plans to return the agency’s Boeing Crew Flight Test from the International Space Station in the coming weeks.

Teams completed ground hot fire testing at White Sands and are working to evaluate the test data and inspect the test engine. The ongoing ground analysis is expected to continue throughout the week. Working with a reaction control system thruster built for a future Starliner spacecraft, ground teams fired the engine through similar inflight conditions the spacecraft experienced on the way to the space station. The ground tests also included stress-case firings, and replicated conditions Starliner’s thrusters will experience from undocking to deorbit burn, where the thrusters will fire to slow Starliner’s speed to bring it out of orbit for landing in the southwestern United States. For a detailed overview of the test plans, listen to a replay of a recent media teleconference with NASA and Boeing leadership.

“I am extremely proud of the NASA, Boeing team for their hard work in executing a very complex test series,” said Steve Stich, manager, NASA’s Commercial Crew Program. “We collected an incredible amount of data on the thruster that could help us better understand what is going on in flight. Next, our team has moved into engine tear downs and inspections which will provide additional insight as we analyze the results and evaluate next steps.”

Integrated ground teams also are preparing for an in-depth Agency Flight Test Readiness Review, which will evaluate data related to the spacecraft’s propulsion system performance before its return to Earth. The date of the agency review has not yet been solidified.

NASA and Boeing leadership plan to discuss the testing and analysis work in detail during a media briefing next week. More information on the briefing will be made available soon.

While testing and analysis are happening on Earth, NASA astronauts Butch Wilmore, Starliner mission commander, and Suni Williams, mission pilot, are working alongside the Expedition 71 crew. The two participated in vein scans using the Ultrasound 2 device on Monday. Doctors on the ground monitored in real-time as the pair took turns imaging each other’s neck, shoulder, and leg veins. Afterward, Wilmore scanned the veins of fellow NASA astronaut Matthew Dominick, helping researchers understand how microgravity affects the human body.

Wilmore and Dominick also spent a portion of the day taking inventory of the food stored aboard the space station. Williams worked on a pair of studies, first exploring the use of microgravity to manufacture higher-quality optical fibers than on Earth. Williams also investigated using fluid physics, such as surface tension, to overcome the lack of gravity when watering and nourishing plants grown in space.

During a media teleconference Friday, leaders from NASA and Boeing provided an update about Starliner’s Crew Flight Test. The integrated Starliner team continues to evaluate the spacecraft’s propulsion system performance and complete other forward work before scheduling undocking from the International Space Station. Listen to a full replay of the teleconference.

“Our goal is to bring Butch and Suni home aboard Boeing’s spacecraft, and we are working to confirm Starliner will perform as designed to return them safely to Earth,” said Ken Bowersox, associate administrator, NASA’s Space Operations Mission Directorate, NASA Headquarters in Washington. “Space station gives us the luxury of time, allowing us to look at data we gathered on the way uphill and conduct some additional testing. We’re still in the middle of a test mission, and we want to spend more time with the data before we make the final call to put the crew aboard the spacecraft for return.”

NASA and Boeing will conduct additional ground testing at White Sands Test Facility in New Mexico to better understand the spacecraft’s thruster performance. This testing will expose Starliner’s thrusters to flight-like pulse counts and thermal conditions for ground teams to inspect and analyze. The data collected also will help determine system improvements for future post-certification missions to station.

“We spent a lot of time working to determine whether we could get meaningful data from a ground hot fire to better inform our decision making in flight, and I am extremely proud of our integrated NASA and Boeing teams for coming up with some innovative options and leveraging testing plans that were already in place for future missions,” said Steve Stich, manager of NASA’s Commercial Crew Program. “Based on the continued performance of Starliner while docked, we are working with station to extend the certification of several components beyond a 45-day mission duration, if needed, so our engineering teams can take the time they need while Butch and Suni support various in-orbit activities that are critical for sustaining station operations and research.”

Engineering teams are working to finalize testing plans and a timeline for the additional ground testing, which should occur over the next two weeks. They are taking advantage of the extra time by gathering as much data as possible while docked to station, considering the service module will not be recovered at the end of the mission.

Since Starliner’s arrival on June 6 with NASA astronauts Butch Wilmore and Suni Williams aboard, mission teams have been working to complete open work related to managing five small leaks in the spacecraft’s service module helium manifolds while reaffirming the health of the spacecraft’s reaction control system thrusters. Starliner remains available in case of an emergency on the space station that would require the crew to leave orbit immediately and return to Earth.

In addition to monitoring the hardware in orbit, which is operating normally in a docked state, NASA and Boeing continue testing and analysis on the ground by exploring potential causes for the helium system leaks and analyzing instrumentation data on Starliner’s thrusters. Engineers are working to gauge potential helium leak rates that may occur after undocking, validate operational mitigations for use in flight as needed, and explore fault tree considerations beyond what the teams have already gathered from the flight data.

They also are evaluating recent ground test results that showed better than expected performance of Starliner’s thruster instrumentation. Based upon these results, engineering teams have confidence that Starliner’s thruster pressure transducers are not overheating in flight and causing premature deselects of the thrusters in orbit, which was initially considered to be a possibility. Meanwhile, simulated propulsion system contingency scenarios continue to be worked in the lab to ensure expected performance of Starliner’s backup systems and thruster combinations for use during the return if needed.

Once all the necessary ground testing and associated data analysis is complete, leaders from NASA’s Commercial Crew and International Space Station Programs and Boeing will conduct an agency-level review. During the review, senior agency leaders and mission managers will discuss their findings and options with the broader NASA community, including international partners, to formally document the agency’s acceptance of Starliner’s flight plan and evaluate future return opportunities.

NASA plans to host a televised media briefing following the agency review to discuss the next steps ahead of Starliner’s return. The agency will share details on that briefing once it is finalized.

Wilmore and Williams continue to provide additional crew time and valuable contributions aboard the space station, assisting with spacewalks and science investigations while helping ground teams collect critical data for post-certification, long-duration Starliner flights to the orbiting complex.

NASA astronauts Matthew Dominick, commander; Michael Barratt, pilot; and mission specialist Jeanette Epps, as well as Roscosmos cosmonaut mission specialist Alexander Grebenkin are on their way to the International Space Station, following the picture-perfect launch of the agency’s SpaceX Crew-8 mission. SpaceX’s Dragon spacecraft, named Endeavour, launched at 10:53 p.m. EST atop the company’s Falcon 9 rocket from the agency’s Kennedy Space Center’s Launch Complex 39A in Florida.

“I want to personally thank the crew for their work and the sacrifice that they’ve made of their time to train and be ready for this mission,” said NASA Associate Administrator Jim Free. “Crew-8’s mission will further the understanding of how humans learn and behave in space and how their bodies respond, and it’s all critical to our lunar exploration. We need all of these to come together to understand how people and technologies and systems will behave when we go on longer duration missions.”

Once in orbit, the crew and SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually, if necessary.

Upon arrival, the members of Crew-8 will be welcomed inside the station by the seven-member crew of Expedition 70 and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-7 mission. After the handover period, NASA astronaut Jasmin Moghbeli, ESA (European Space Agency) astronaut Andy Mogensen, JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa, and Roscosmos cosmonaut Konstantin Borisov of Crew-7 will undock from the space station and splash down off the coast of Florida.

“We’ll have five dock days of Crew-8/Crew-7 handover activities, after which we’ll start watching weather and look for a landing opportunity for Crew-7,” said Joel Montalbano, NASA program manager, International Space Station. “Crew-8 will stay onboard the International Space Station until mid-August, performing over 200 experiments in science and research, technology development, and commercialization of low-Earth orbit.”

The members of Crew-8 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include using stem cells to create organoid models to study degenerative diseases, studying the effects of microgravity and UV radiation on plants at a cellular level, and testing whether wearing pressure cuffs on the legs could prevent fluid shifts and reduce health problems in astronauts. These are just a few of the more than 200 scientific experiments and technology demonstrations taking place during their mission.

At the end of their mission, Crew-8 will complete a short handover with Crew-9, and the Dragon spacecraft – with the four crew members aboard – will autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off of Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore.

“What a crazy exciting time in space right now,” said Free. “And it’s all rooted in NASA’s mission of exploring the unknown in air and space, innovating for the benefit of humanity, and inspiring the world through discovery. The four individuals of Crew-8 exemplify that.”

The agency’s SpaceX Crew-8 mission is the eighth commercial crew rotation mission for NASA.
